Let's divide 36782507 by 25
The aim is to understand the frequency of 25 in 36782507.

Moving on to step 1:
3 divided by 25 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 25

On to step 2:
If we divide 36 by 25, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 25 from 36 to get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 25

Step 3:
117 divided by 25 is 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 100 from 117, we get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 25

Step 4:
178 divided by 25 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Subtracting 175 from 178 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 25

Going ahead to step 5:
If we divide 32 by 25, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1471.0
The remainder is 7 after subtracting 25 from 32.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 25

Step 6:
If we divide 75 by 25, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 14713.0
Deduct 75 from 75 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 25

Going ahead to step 7:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 147130.0
Subtract 0 from 0 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 25

Going ahead to step 8:
7 divided by 25 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 1471300.0
Subtracting 0 from 7 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 25 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1471300.2
Subtracting 50 from 70 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 25 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1471300.28
Deduct 200 from 200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1471300.28
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1471300.28
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1471300.28 with a remaining 0.0.
